ABS Indicator

The IPC illuminates the ABS indicator when the following occurs:

• The electronic brake control module (EBCM) detects a malfunction with the anti-lock brake system. The IPC receives a class 2 message from the EBCM requesting illumination.
• The IPC performs the displays test at the start of each ignition cycle. The indicator illuminates for approximately 3 seconds.

The IPC sends a class 2 message to the radio for audible warning when this indicator is on.
